Method of synchronizing the engines of an aircraft

摘要

A method of synchronizing engines of an airplane in accordance with at least one activation logic (10, 10′) defining a deactivated state (20), a primed state (22), and at least one activated state (16, 18), and comprising:
passing (32) synchronization from the deactivated state to the primed state when a pilot of the airplane issues an activation order;passing (36) synchronization from the primed state to the activated state when at least certain safety and/or activation conditions are satisfied; andpassing (24, 34) synchronization from the activated or primed state to the deactivated state when the pilot issues a deactivation order or whenever at least some of the safety conditions are not satisfied.

1. A method of synchronizing engines of an airplane by an electronic chip encoding at least one activation logic for verifying safety and/or activation conditions in order to apply synchronization to the engines, wherein the activation logic defines synchronization states of the engines including at least a deactivated state, a primed state, and an activated state, the method comprising:
receiving, with the electronic chip, an activation order issued by a pilot of the airplane; outputting, with the activation logic encoded on the electronic chip, a command to pass a synchronization state of the engines from the deactivated state to the primed state when the activation order issued by the pilot is received; determining, with the activation logic encoded on the electronic chip, whether the safety and/or activation conditions are satisfied or not satisfied, by periodically verifying whether the safety and/or activation conditions meet predetermined thresholds or predetermined operation states of the engines or of the airplane; outputting, with the activation logic encoded on the electronic chip, a command to pass the synchronization state of the engines from the primed state to the activated state when certain of the safety and/or activation conditions are satisfied; receiving, with the electronic chip, a deactivation order issued by the pilot, or determining that certain of the safety conditions are not satisfied; and outputting, with the activation logic encoded on the electronic chip, a command to pass the synchronization state of the engines from the activated state or the primed state to the deactivated state when the deactivation order issued by the pilot is received or whenever it is determined that the certain of said safety conditions are not satisfied.
